180 Ton double compressors water cooled screw chiller 

180 Ton water cooled screw chiller double compressors cooling systems use Famous brand semi-hermetic screw compressor Hanbell from Taiwan or Bitzer from Germany. water cooled screw chillers are effective cooling solutions for industrial processes as well as making for efficient air conditioning systems for large facilities like office buildings, schools, theaters, factories, warehouses, shopping malls, libraries, etc. In these applications chillers use less power than traditional air conditioning methods. 

Oumal Refrigeration is a leading water cooled screw chiller supplier in china. Using famous brand Semi-hermetic Screw Compressor- Bitzer from Germany and Handbell from Taiwan.

Each screw compressor comes with 4 steps of energy control 0-25%-50%-75%-100% to make sure the whole screw chiller operates when stable with high refrigeration performance.

Each water-cooled screw chiller with high-efficiency shell and tube type heat exchanger and shell and tube condenser.

Integrated PLC control system with human-computer interface and big LED touch screen panel for easy operation.

Other refrigeration parts are world famous refrigeration spare parts like Danfoss or Emerson thermal expansion valve, Alco dryer filter, Schneider contactor, and overload relay will make sure the whole screw chiller works under normal condition.

Compared with air cooled screw chiller, water cooled screw chiller should run together with external cooling tower and water pump. This is the biggest difference between air cooled screw chiller and water cooled screw chiller.

Besides the standard water-cooled screw chiller control temperature from 7ºC to 30ºC, OUMAL chiller also has a water-cooled glycol screw chiller control temperature below zero from 0ºC to -40ºC for some special industrial applications.As a professional water cooled screw chiller manufacturer, OUMAL Chiller has exported many water cooled screw chillers to the Philippines, Australia, New Zealand, Malaysia, Singapore, Indonesia, Chile, Mexico, Costa Rica, Brazil, Argentina, Colombia, South Africa, Nigeria, Saudi Arabia, Dubai, Spain, Italy, etc.
